摘要： There is provided a combined cycle power plant in which a high-pressure steam turbine and an intermediate-pressure steam turbine can operate in a state where amounts of thermal effect thereof are close to a limit value, and capable of reducing start-up time. A combined cycle power plant includes: an exhaust heat recovery boiler that includes a high-pressure superheater which superheats steam for a high-pressure steam turbine, and a reheater which reheats steam for an intermediate-pressure steam turbine; bypass pipes through which steam bypasses the high-pressure superheater and the reheater; bypass valves that regulate flow rates of steam which flows through the bypass pipes; and a bypass controller that controls the bypass valves such that a difference between thermal effect-amount margins of the turbines is decreased.

摘要： A Rankine cycle system mounted on a vehicle includes a Rankine cycle circuit, a pressure detector, a temperature detector and a controller. The Rankine cycle circuit includes a fluid expansion device, a fluid transferring device, first and second passages, a heater, a cooling device, a bypass passage and a flow regulating valve. The bypass passage connects the first passage and the second passage, and in which the flow regulating valve is provided for opening and closing the bypass passage. The controller is connected to the flow regulating valve for controlling an operation of the flow regulating valve and to the pressure and temperature detectors and for receiving signals of pressure and temperature from the pressure and temperature detectors, respectively. The controller controls the operation of the flow regulating valve based on a superheat degree of the working fluid calculated from the signals of the pressure and temperature.

摘要： The invention is concerned with an improvement in a steam turbine having a boiler having a first superheater, a first conduit having an inlet end and an outlet end, said outlet end being connected to said first superheater, a pressurized liquid working fluid source connected to said inlet end of said first conduit, said first superheater being adapted to convert said liquid working fluid to superheated vapor, a second conduit having an input end and an output end, said input end being connected to receive said vapor from said superheater, and a turbine connected to receive said vapor from said output end of said second conduit. The improvement comprises a structure for restricting flow through the second conduit. A third conduit is adapted to conduct a first portion of the superheated vapor from the second conduit from downstream of the restricting structure to a second superheater wherein the first portion of the superheated vapor is further superheated. The fourth conduit is adapted to conduct the further superheated vapor from the second superheater to the turbine. The result is improved utilization of the heat generated by the boiler whereby significant increases in output energy result.
